Cannot visualize github.com/alecthomas/gozmq #27

Closed iselind closed 6 years ago

iselind commented 6 years ago

github.com/alecthomas/gozmq seems problematic for go-callvis to handle. I'm guessing because gozmq require cgo. 

# % is my prompt
# Get the source, this works great, i have the libzmq3-dev deb-package installed on my machine
% go get -tags zmq_3_x github.com/alecthomas/gozmq
# The following command complain that various symbols are not declared. They are declared, but in the C part of package
% go-callvis github.com/alecthomas/gozmq
# go-callvis show the help pages when i do the following, missing feature?
% go-callvis -tags zmq_3_x github.com/alecthomas/gozmq

Is there any work ongoing to fix this?

I'll look into this and let you know. I also accept PR if you'd like to implement this.

Hey @iselind the -tags flag is included in the upcoming changes. You can find it in opened PR here: https://github.com/TrueFurby/go-callvis/pull/29 with several other improvements.

The call graph output is now served via HTTP server in SVG format and you can click on packages to change focus.

I'll try it as soon as I can. I'll let you know!
